I was trying to understand what you're saying, below, about replacing the
(cr & cr) with cr, and don't see where you're referring to this in the
original suggestion I'm working with. It is likely I missed something
(important).
In the original question, IIRC you wanted to strip extra returns and leading spaces from lines of text, particularly HTML. The suggestion to use:
replace (cr&cr) with cr in tData
Is basically saying "whenever you find two consecutive returns, replace them with one". A few passes through and you should find that all of the extra returns are gone.
So something like this might be worth a try:
## put the field data into a variable for fast access put fld "Imported_Raw" into tData
## keep replacing double return until there are none left repeat while (tData contains (cr&cr)) replace (cr&cr) with cr in tData end repeat
## keep replacing leading spaces until there are none left repeat while (tData contains (cr&space)) replace (cr&space) with cr in tData end repeat
There are probably a lot of interesting ways to go about the task- you could also use the replaceText() function with a regular expression to fix the whole thing in one pass. But RegEx isn't always fun...
It would be awesome to get times like 5 seconds, but I must admit that I'll
be happy to just get it in the 'couple-of-minutes' range!
One of the lines provided to me says:
repeat for each line tLine in tData
As I'm working with further 'massaging' of the grabbed text, I'm playing
with some of this code and this one left me scratching my head (and there
ain't a lot of hair up there!) -- what is the function of the (variable?)
tLine in this text? I didn't see it previously declared in the script and
wondered why this wouldn't simply be:
repeat for each line in tData
Instead. Again, I'm sure I missed something important, but I really AM paying attention.
Think of the above syntax as a replacement for the slower (but still available) syntax:
repeat with i=1 to (number of lines in tData) put line i of tData into tLine ... end repeat
Instead of using a counter variable, and also gaining lots of speed, you can just write:
repeat for each line tLine in tData ... end repeat
The results will be exactly the same- except that the second will run much faster and syntax-wise, serves as a sort of shorthand for the former.
I also wanted to comment that one of the reasons I decided to go with
Revolution instead of any of the other suggestions is the tone and
helpfulness of the members of this list. I'm glad to be a member of a list
where everyone seems to want to share ideas, rather than berate the newbies
or 'one-up' the others on the list. Hopefully the developers remember those
who bought in at the ground floor when they're rich and famous... (For
those of you who've been around the Mac arena since 1983 (yes, I said "3"),
think HyperCard, and FirstClass, etc.)
Amen! I think you'll find there's a real mix here: quite a few old Hypercard hats mixed in with a little of everything else. Personally, I can only trace my Hypercard roots back to about 1992, but in my defense, I was 3 years old for the majority of 1983...
